Hi everyone,

Someone knows if the MKR1300 has a RTC module ? If the answer is yes, can the RTC module remember the last date and the last hour after shut down the MKR1300 board ?

Thanks,

Alexis

Hello Alexis, yes it has an internal RTC module.
You can use it with <RTCZero.h> (RTCZero - Arduino Reference).
No, it doesn't remember the last time and date, but you can read it and save in some non-volatile memory.

Hi Alexis,

I am working on some "issues" with the RTCZero library now. In particular, the low power performance of the library. Keep an eye on github, I will likely make a PR soon.
